Description

Technical Field

[0001] The utility model relates to the technical field of suction cup jigs, and particularly relates to a robotic arm suction cup jig. Background Art

[0002] A robotic arm suction cup jig is an automated device that uses the principle of vacuum adsorption to achieve workpiece grasping and handling. Robotic arm suction cup jigs are widely used in automated production lines and industrial processing, and are applicable to fields such as automotive manufacturing, electronic manufacturing, medical device manufacturing, and food packaging. It is particularly suitable for handling flat or slightly convex objects, such as glass plates, plastic sheets, etc., and has the characteristics of stable grasping and no damage to the surface of the object. It usually consists of a bracket, a suction cup assembly, a vacuum system, and a control system. The suction cup is the core part of the jig, usually made of soft rubber or silica gel, used to generate a vacuum and adsorb on the surface of the workpiece, and make full contact with the workpiece surface using the ductility of rubber or silica gel. The bracket is used to fix and support the suction cup, the vacuum system is responsible for creating negative pressure in the suction cup, and the control system is used to monitor and adjust the operation of the vacuum suction cup jig.

[0003] When the existing robotic arm suction cup jig adsorbs and clamps a paper-packaged object, the downward movement amount of the suction cup driven by the robotic arm will exceed a part of the paper-packaged object, causing the bottom end of the suction cup to protrude beyond a part of the paper-packaged object, and the suction cup generates pressure on the paper-packaged object. Such an operation will make the suction cup contact the paper-packaged object more tightly, preventing a gap from being generated between the suction cup and the paper-packaged object, resulting in the inability to generate negative pressure inside the suction cup and the inability to adsorb the paper-packaged object. Although this operation method can improve the adsorption of the suction cup to the paper-packaged object, the distance that the suction cup descends beyond the paper-packaged object has a downward applied pressure, and the suction cup may damage the product inside the paper-packaged object after descending. To solve this technical problem, the utility model proposes a robotic arm suction cup jig. Summary of the Utility Model

[0004] The main purpose of the utility model is to provide a robotic arm suction cup jig, which can effectively solve the problems mentioned in the background art.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] A robotic arm suction cup fixture, comprising a main beam, a support beam, a connecting pipe and a suction cup body. The support beam is arranged below the main beam. A sliding seat is slidably connected to the outer surface of the support beam. A locking bolt is threadedly connected to the inner side of the sliding seat. One end of the locking bolt contacts the inner bottom wall of the support beam. A support seat is connected to the outer surface of the sliding seat. A sliding sleeve is connected to the lower surface of the support seat. A chute is formed inside the sliding sleeve. A pressure plate is slidably connected to the inner wall of the chute. A positioning nut is threadedly connected to the outer surface of the sliding sleeve. The connecting pipe is arranged inside the sliding sleeve. A support ring is connected to the outer surface of the connecting pipe. The outer surface of the support ring is slidably connected to the inner wall of the sliding sleeve. A spring is sleeved outside the connecting pipe. The suction cup body is connected to the bottom end of the connecting pipe.

[0007] Preferably, a positioning groove is formed inside the sliding sleeve. A positioning guide rail is connected to the outer surface of the support ring. The outer surface of the positioning guide rail is slidably connected to the inner wall of the positioning groove.

[0008] Preferably, a support shaft is connected to the inner wall of the pressure plate. A roller is rotatably connected to the outer surface of the support shaft. The outer surface of the roller contacts one side of the positioning nut.

[0009] Preferably, one end of the spring is connected to one side of the pressure plate, and the other end of the spring is connected to one side of the support ring.

[0010] Preferably, an air inlet nozzle is connected to the top end of the connecting pipe, and the air inlet nozzle is located outside the support seat.

[0011] Preferably, a connecting disc is installed on the outer surface of the main beam. An arc-shaped connecting hole is formed inside the connecting disc.

[0012] Preferably, a fixed angle bracket contacts the outer surface of the main beam. The other side of the fixed angle bracket contacts the outer surface of the support beam. Fasteners penetrate through the inside of the fixed angle bracket. There are two fasteners. One fastener is connected to the inside of the main beam, and the other fastener is connected to the inside of the support beam.

[0013] Compared with the prior art, the present utility model has the following beneficial effects:

[0014] In the present utility model, through the cooperation among the spring, the support ring, the pressure plate and the connecting pipe, the position of the pressure plate is adjusted by the positioning nut. After the pressure plate moves, the moving spring contracts, changing the elastic force output of the spring. The connecting pipe receives the elastic supporting force of the spring through the support ring. Through the elastic support of the spring, the suction cup can elastically contract after contacting the paper-packaged object, forming an elastic contact when the suction cup contacts the paper-packaged object, preventing the suction cup from making hard contact with the paper-packaged object and damaging the product inside the paper-packaged object.

[0015] In the present utility model, through the cooperation among the positioning groove, the positioning guide rail, the air inlet nozzle and the connecting pipe, the sliding direction of the positioning guide rail is guided by the positioning groove to prevent the support ring from rotating. The support ring restricts the rotation of the connecting pipe, enabling the connecting pipe to only have the moving function of sliding up and down, preventing the connecting pipe from rotating, and improving the sealing effect of the air inlet nozzle.

Detailed Embodiment

[0022] To make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the present utility model will be further elaborated below in conjunction with specific embodiments.

[0023] As Figures 1-5 shown, a robotic arm suction cup fixture includes a main beam 1, a support beam 2, a connecting pipe 3 and a suction cup body 4. The support beam 2 is arranged below the main beam 1. The outer surface of the support beam 2 is slidably connected with a sliding seat 5. The inner side of the sliding seat 5 is threadedly connected with a locking bolt 22. One end of the locking bolt 22 is in contact with the inner bottom wall of the support beam 2. By driving the suction cup body 4 to move its position through the sliding function of the sliding seat 5, it can adapt to paper packaging objects of different sizes and specifications. After adjusting the position of the sliding seat 5, the movement position of the sliding seat 5 is restricted by rotating the internal locking bolt 22 to maintain the stability of the sliding seat 5.

[0024] The outer surface of the sliding seat 5 is connected to a support seat 6, and the lower surface of the support seat 6 is connected to a sliding sleeve 7. Through the sliding sleeve 7, the connecting pipe 3 has a space for vertical sliding. A sliding groove 8 is provided inside the sliding sleeve 7, and the inner wall of the sliding groove 8 is slidably connected to a pressure plate 9. Through the sliding groove 8, the stability of the pressure plate during sliding is maintained, and at the same time, the sliding direction of the pressure plate 9 is guided.

[0025] The outer surface of the sliding sleeve 7 is threadedly connected to a positioning nut 10. The inner wall of the pressure plate 9 is connected to a support shaft 15. The outer surface of the support shaft 15 is rotatably connected to a roller 16. The outer surface of the roller 16 is in contact with one side of the positioning nut 10. By rotating the positioning nut 10, the pressure plate 9 is pushed to move its position. After the pressure plate 9 moves its position, the telescopic length of the spring 12 is changed. By moving the position of the pressure plate 9, the elastic force output of the spring 12 is adjusted. The spring 12 changes the elastic force output to the connecting pipe 3. The pressure plate 9 contacts the nut through the roller 16 to reduce the frictional force, facilitating the positioning nut 10 to push the pressure plate 9 to move its position.

[0026] The connecting pipe 3 is arranged inside the sliding sleeve 7. The outer surface of the connecting pipe 3 is connected to a support ring 11. Through the support of the support ring 11 for the connecting pipe 3, the stability of the connecting pipe 3 during sliding is maintained. The outer surface of the support ring 11 is slidably connected to the inner wall of the sliding sleeve 7. A spring 12 is sleeved outside the connecting pipe 3. The suction cup body 4 is connected to the bottom end of the connecting pipe 3. One end of the spring 12 is connected to one side of the pressure plate 9, and the other end of the spring 12 is connected to one side of the support ring 11. Through the spring 12, elastic support is formed for the support ring 11. After the suction cup body 4 contacts the paper packaging object, the connecting pipe 3 is pushed to slide upward. While the connecting pipe 3 slides, the support ring 11 is pushed to slide upward. The support ring 11 squeezes the spring 12 to contract, and at the same time, the spring 12 forms an elastic driving force for the support ring 11, pushing the suction cup body 4 to tightly contact the paper packaging object.

[0027] A positioning groove 13 is provided inside the sliding sleeve 7. The outer surface of the support ring 11 is connected to a positioning guide rail 14. The outer surface of the positioning guide rail 14 is slidably connected to the inner wall of the positioning groove 13. Through the positioning groove 13, the sliding direction of the positioning guide rail 14 is guided, preventing the support ring 11 from rotating, so that the support ring 11 only has the function of vertical sliding.

[0028] The top end of the connecting pipe 3 is connected to an air inlet nozzle 17, and the air inlet nozzle 17 is located outside the support seat 6. The air inlet nozzle 17 is connected to a hose, and a vacuum device is connected through the hose. After the suction cup body 4 contacts the paper packaging object, the air inside the suction cup body 4 is pumped out through the vacuum device, so that a vacuum is formed inside the suction cup body 4 to adsorb the paper packaging object.

[0029] A connection plate 18 is installed on the outer surface of the main beam 1. An arc-shaped connection hole 19 is provided inside the connection plate 18. The connection plate is connected to the robotic arm through the arc-shaped connection hole 19 inside the connection plate, and the arc-shaped connection hole 19 can adjust the connection angle between the connection plate and the robotic arm.

[0030] A fixed angle code 20 is in contact with the outer surface of the main beam 1. The other side of the fixed angle code 20 is in contact with the outer surface of the support beam 2. A fastener 21 is penetrated and connected inside the fixed angle code 20. There are two fasteners 21. One of the fasteners 21 is connected to the inside of the main beam 1, and the other fastener 21 is connected to the inside of the support beam 2. The connection stability between the main beam 1 and the support beam 2 is increased through the fixed angle code 20. The fastener 21 includes a nut and a bolt. The bolt forms a tensile force inside the through grooves of the main beam 1 and the support beam 2. The bolt cooperates with the nut to lock the fixed angle code 20, so that the support beam 2 and the main beam 1 form an integral body.

[0031] It should be noted that during the actual use of this device, during use, first the suction cup body 4 moves above the paper-packaged object, and then the suction cup body 4 descends to contact the paper-packaged object. After the suction cup body 4 contacts the paper-packaged object, it pushes the connecting pipe 3 to move upward. At the same time, the connecting pipe 3 drives the support ring 11 to move upward. The support ring 11 simultaneously pushes the spring 12 to contract. Subsequently, the suction cup body 4 forms an adsorption and clamping on the paper-packaged object.
